Abstract
The utility model relates to a plasma cutting machine specifically discloses a plasma cutting torch. The technical problems of high operation cost and short maintenance period of the existing plasma cutting torch are solved. The technical scheme of the utility model including the rifle head, install the electrode at rifle head front end, still include and fix the rotatory ring on the rifle head through fixed lid, rotatory ring front end is provided with nozzle and fixed cover, electrode pitch be 2.04 millimeters. The screw pitch of the electrode is increased, so that the circulating gas circulation time is shortened, the cooling effect is better, the service life of the electrode is prolonged, and the maintenance period of the plasma cutting torch is prolonged; meanwhile, the use efficiency of the compressed air is improved, the load of the air compressor is reduced, and the operation cost is saved.
Description
Technical field
The utility model relates to CUT, is specifically related to a kind of plasma cutting-torch.
Background technology
The plasma cutting is that air is passed through hf electric arc " decomposition " or ionization, becomes basic atomic particle, thereby produces plasma, utilizes the formed high temperature of nozzle compression arc, the high speed plasma jet of small-bore to do the method that thermal source carries out fusion cutting in the cutting.Cutting torch is the vitals of CUT, also is simultaneously to be prone to wearing detail.Cutting torch needs to import compressed air and cools off in the process of work, compressed air gets into cutting torch through the rifle head, circulates to reach cooling effect along the spiral that is provided with on the electrode.The helical pitch of existing cutting torch electrode has only 1.49 millimeters and 1.69 two kinds of specifications, because pitch is little, and the path length of gas walking, so gas circulation efficient is low, and the air compressor machine load is big in the operation process, and use cost is higher; Because cooling effect is relatively poor, electrode is prone to loss, has increased the frequency of maintenance of cutting torch simultaneously.
Summary of the invention
The purpose of the utility model with the plasma cutting-torch that provides that a kind of operating cost is low, maintenance period is long.
For achieving the above object, the technical scheme of the utility model comprises the rifle head, is installed in the electrode of rifle head front end, also comprises through fixed cap being fixed on the rotating ring on the rifle head, and the rotating ring front end is provided with nozzle and fixed cover, and described electrode pitch is 2.04 millimeters.
After having adopted technique scheme, owing to increased the pitch of electrode, thus making recyclegas shortening circulation timei, cooling effect is better, has prolonged the life-span of electrode, has increased the maintenance period of plasma cutting-torch; The compressed air service efficiency improves simultaneously, has reduced the air compressor machine load, has saved operating cost.
Illustrate
Fig. 1 is the sketch map of the utility model plasma cutting-torch;
Fig. 2 is the partial schematic diagram of electrode embodiment illustrated in fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model plasma cutting-torch is done further explain.
Visible like Fig. 1, present embodiment comprises rifle head 1, is installed in the electrode 3 of rifle head 1 front end, also comprises through fixed cap 2 being fixed on the rotating ring 4 on the rifle head 1, and rotating ring 4 front ends are provided with nozzle 5 and fixed cover 6; Visible like Fig. 2, the pitch of described electrode 3 is P, P=2.04 millimeter in the present embodiment.
The pitch of the utility model electrode is set to 2.04 millimeters, because appropriateness has increased the pitch of electrode, thereby makes recyclegas shortening circulation timei, and cooling effect is better, has prolonged the life-span of electrode, has increased the maintenance period of plasma cutting-torch; The compressed air service efficiency improves simultaneously, has reduced the air compressor machine load, has saved operating cost.
